To all @nimmt-z5 mcy concer/1i: Y

.de it known that L'Gnonen R. BROWN, a citizen of 'the United States,residing at Los ngeles, in the county of Los Angeles vand, tate ofCalifornia, have invented neiv and useful improvements is Valve Caps, etwhich. the -following isl specification.

My invention relates to valve caps for enclosing valve Steins ofpneumatic vehicle ires, and has for its object to provide a cap for thispurpose which may be quickly and easily removed from, or securelyattached to a valve stein when it is desired to ll the 'tire ivitli air.

1n tlie drawings 4 Fig. 1 is an enlarged longitudinal section throughiny cap construction, as it Would appear ivlien applied to a valvestern.

Fig. 2 is a transverse section of the saine, taken on the line 2--2 ofFig. 1.

En carrying out niy invention, 5 represents the felly of a Wheel, whichis provided. with an aperture 6 through vvhicli the valve stein 7projects, lthe end S of which is provided with the usual valve (notshown), and the end 9 of which is connected in the usual manner With theinner tube of the tire (not shown).

Secured to the valve stein 7, and adapted to rest against the innerperiphery of the Wheel :telly 5 is a threaded jain nut 10, having anenlarged bore 11 into which is mounted a sleeve .12 having on each ofits ends an extending annular flange 13, he outer surfaces of saidflanges adapted to fit tightly inte the bore 11 in pressed' relationtherewith, thus fiinily securing said nut and sleeve together andforming an annular recess or pocket 1-1- in the nut 10, as clearlyshoivn in 1 of 'the drawings.

The bore l5 oi sleeve 12 is of larger dianieter than the diameter' ofthe valve stern 8. thus forming an annular channel 16 betvveen thesleeve 12 and said valve stern. Sleeve 12 has a plurality of aperturessecond fiange 23.` is fornied on the cap 20 a l suitable distance` abovethe flangev 22 and is ofv greater diameter than the vbore 15 of sleeve12 and is adapted to rest on said sleeve. i y l Then the cap isassembled .to the valve stern as shoivn in the dravvingait will be seenthat the flange 22 on said dust cap projects under the vspring pressedballs 18, which serve as latches, thus firmly locking the dust cap inposition around the valve stem. When it is desired to reniove the cap 2Oit is only necessary to exert a pull upon it in the direction indicatedby the arrow A in Fig. 1 of the drawings, of sufficient force toovercome the tension of the spring ring 19, thus causing the balls 18 toyield outwardly and allovv the flange 22 to pass by theni. f lilhen itis desired to replace the dust cap tlie flange 22 is inserted into thebore 15 and upon pressure the lower outer edge cf said flange engagesWith the balls 18 and forces thein outwardly against the pressure of thespring 19, tlius allowing the flange to pass between the balls and toagain becoine locked under tlieni.

What I claim is:

1. The combination with the'felly of a Wheel and a valve stein extendingtherethrough, of a recessed nut threaded on to said steni, a pluralityoit radially disposed latches mounted in the recess fornied in said nut,a dust cap provided at its end with an annular flange adapted to engagewith said latches, and a spring ring niounted in the recess of said nutand adapted to press all of said latches into engagement vritlfi saidflange.

2. The combination with the telly of a Wheel and a 'valve sternextending therethrough, oi a nut provided with an enlarged bore threadedon said stein, a plurality of radially disposed balls mounted in saidbore, a tubular cap provided at one of its ends with a flange adapted toengage under said balls, and a flat spring ring adapted to engage withand surround said balls, whereby said balls will loe yieldingly held inengagement with said flange.

3. rilie combination with the telly of' a Wheel and a valve stemextending therethrough, of a nut threaded to said valve steni providedwith an enlarged bore having a sleeve secured therein, the Wall of saidsleeve being` provided Wit-ha plurality of apertures having ballsdisposed therein and projecting beyondboth the inner and outer surfacesof said sleeve, a spring ring,` adapted to surround said balls andcontact therewith, and a tubular cap provided et one of its ends with aflange adapted to Surround said stem and to engage With said bells,whereby said cap Will become yeldingly looked to said stem and coller.

4. In Combination with the elly of a Wheel and a valvestem extendingtherethrough, of a; nut threaded on to said stem, seid nut provided`with an annular reeess in one end thereonv an rinnulzir lenged sleeveprovided in its Walls with a plurality of tapered apertures for thereception of balls7 and e flat spring ring` mountedin said sleeve anddisposed between said flanges and engaging said balls 'to normally Seatthe same in the tapered apertures, said sleeve mounted tightly in theannular recess formed in the nut7 and i 'tubular cap provided et one ofits ends with a flange adapted to surround said stem and engage withsaid balls, whereby said cap Will become yieldingly looked to said nut.

In Witness that claim the foregoing I have hereunto subseribi-xdk myname "this 27th day of September, 1921.
